What is included in clearance letter
Thorough. Professional. Built for clear decisions.
Clearance is the final quality-control stage after asbestos abatement. The enclosure and cleaned surfaces must be ready before air sampling begins, and the decision should be made by a party separate from the removal contractor.
Scope review
We confirm the work area and decision the testing must support.
Qualified sampling
Representative samples are collected with controlled methods and clear labels.
Laboratory analysis
Samples go to an appropriately accredited third-party laboratory under documented chain of custody.
Clear documentation
Results are linked to the exact material and location sampled.
Compliance focused
The service follows the project and WorkSafeBC requirements that apply.
Prompt turnaround
Standard and rush laboratory options are coordinated around your schedule.
Testing and verification are separate from the contractor whose work we verify.

Our process
Inspect first. Sample second. Release last. No guesswork.
We review the abatement scope, inspect the enclosure and cleaned surfaces, collect air samples when appropriate, coordinate lab analysis and issue the result package.
- 1
Site walk and inventory
A qualified surveyor walks the property, identifies every suspect material, and maps location and quantity.
- 2
Sampling
We collect bulk samples, and air samples where needed, following WorkSafeBC practice. Homeowner-collected samples are not accepted.
- 3
Accredited lab analysis
Samples go to an appropriately accredited third-party laboratory, with standard turnaround of 1 to 2 business days and rush service available.

Suspect hazardous materials are assessed before they are cut, drilled, removed or disturbed.
- Use a trained professional
The inspection and sampling must be completed by someone qualified for the project decision.
- Connect results to locations
The report makes each finding usable for permit, contractor and owner decisions.

FAQ
Asbestos Clearance Letter clear answers.
Direct answers about clearance letter, reporting, timing and compliance in Metro Vancouver.
An asbestos clearance letter is the written conclusion of post-abatement verification. It identifies the project and inspected area, summarizes the visual inspection and any required sampling, and states the release decision. It does not replace the underlying inspection, chain-of-custody records or third-party laboratory results that support the conclusion.
